logging - PowerShell Log Function Readability -


currently log function spits out information in single column , hard read. there way make split different columns each (displayname, poolname, poolsnapshot, , desktopsvivmsnapshot) , respective information put correctly?

function log ([string]$entry) {     write-output $entry | out-file -append "c:\logs\snapshot.csv" }  add-pssnapin quest.activeroles.admanagement  $date = get-date -format "mm-dd-yyyy" $time = get-date -format "hh:mm:sstt"  # begin log log $(get-date) log "the below desktops not using correct snapshot."   if (@($desktopexceptions).count -lt 1) {     write-output "all desktops in $pool using correct snapshots." |         out-file -append "c:\logs\snapshot.csv" } else {     write-output $desktopexceptions |         select-object displayname,poolname,poolsnapshot,desktopsvivmsnapshot |         sort displayname |         out-file -append "c:\logs\snapshot.csv" }  log $(get-date) 
 09/11/2017 12:16:17  displayname   poolname       poolsnapshot                            desktopsvivmsnapshot -----------   --------       ------------                            -------------------- xxxc-13v      xxxc-xxx       /8-11-2017/09-07-2017                   /8-11-2017 xxxc-15v      xxxc-xxx       /8-11-2017/09-07-2017                   /8-11-2017 xxxc-1v       xxxc-xxx       /8-11-2017/09-07-2017                   /8-11-2017 xxxc-20v      xxxc-xxx       /8-11-2017/09-07-2017                   /8-11-2017

note: removed parts of log in hopes not make post long.

csv files require uniform lines: header line column names, followed data lines containing column values.

by writing output get-date first - single date/time string - followed single-string output, followed multi-column output $desktopexceptions | select-object ... call, you're definition not creating valid csv file.

if still want create such file:

log (get-date)  # single command, don't need $(...) - (...) do. log "the below desktops not using correct snapshot."   if ($desktopexceptions)  # non-empty array / non-$null object {   log ($desktopexceptions |     select-object displayname,poolname,poolsnapshot,desktopsvivmsnapshot |      sort-object displayname |       convertto-csv -notypeinformation) } else {   log "all desktops in $pool using correct snapshots." }  log (get-date)

  • by defining log() function's parameter type [string], you're forcing stringification of whatever object pass it. stringification same when embed variable reference or command inside "..." (string expansion / interpolation) - not same default, when print console.

  • out-file, contrast, does result in same output when printing console, which, however, format human consumption, not machine parsing (as csv is, instance).

  • to csv-formatted output, must either use export-csv - write directly file - or convertto-csv- string representation.

  • also note there's typically no reason use write-output explicitly - command / expression's output not explicitly assigned variable / redirected (to file or $null) implicitly sent powershell's [success] output stream; e.g., write-output get-date same get-date.

angular - Ionic slides - dynamically add slides before and after -

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
